Ashcroft 96261 Pressure Gauge 4.5 in Dial 0-400 Psi Rear Flange

Product Description

The ASHCROFT 96261 is an analog pressure gauge designed for accurate pressure monitoring in mechanical, HVAC, plumbing, and industrial service applications. The gauge features a 4.5-inch dial for easy readout and covers a range of 0 to 400 psi with an accuracy rating of 0.5% of scale. The thermoplastic case resists corrosion and impact in typical field conditions. It is a dry, no-fill gauge, meaning no liquid dampening fluid is used, which suits applications where fluid contamination of the gauge internals is a concern. The rear flange mount configuration allows secure panel or surface installation. Licensed tradespeople and maintenance technicians working on pressurized systems will find this gauge straightforward to mount and read.

The ASHCROFT 96261 is suited for residential and light commercial HVAC systems, plumbing installations, compressed air lines, and general-purpose pressure monitoring wherever a mid-range psi gauge with a large dial face is needed. The 0.5-inch thread connection and rear flange mount make it adaptable to standard pipe fittings used in typical service work. It is commonly installed at pressure test points, pump discharge lines, and system monitoring ports where a durable, readable gauge is required.

Key Features

• 4.5-inch analog dial provides clear, at-a-glance pressure readings
• 0 to 400 psi pressure range covers a wide variety of medium-pressure applications
• 0.5% of scale accuracy for reliable monitoring
• Thermoplastic case construction resists corrosion and everyday field wear
• Dry, no-fill design eliminates risk of liquid contamination from gauge internals
• Rear flange mount allows secure flush or panel mounting
• 0.5-inch thread connection matches standard pipe fittings

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for standard 0.5-inch threaded pressure ports in HVAC, plumbing, compressed air, and general mechanical systems requiring a rear flange-mount analog gauge.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor in accordance with applicable local codes and the IFGC or IPC as relevant to the system type. Always depressurize and isolate the system section before removing an existing gauge or installing this unit. Apply an appropriate thread sealant to the male threads per standard practice, but do not over-tighten the thermoplastic-adjacent connection, as case cracking can result from excessive torque. Verify the system operating pressure falls within the 0 to 400 psi range before placing the gauge into service.
